In a nitro it needs to pull the throtle and the throtle return spring on top of pulling the brake. It takes a little more power, plus its constantly under load operating the throtle and the brake. With this mini setup the servo only sees action when I'm on the brake which is probably less than 2% of the time.
Just as an FYI I fried 2 of those Hitec mini servos. I finally found a mini JR DS3421 servo that is holding up well. Its about the same specs as the Hitec, a bit more expensive, but it handles the load better. I also designed a better plate for the servo and brake mounting and had Mike machine it up for me. The whole setup has also been transfered to the XT8 truggy. Ive been running the brake in there all season so far and its holding up great. I actually really like it in the truggy much better than in the buggy. It allows you to drive the corners more with the throttle and brake. The buggy doesnt benefit as much and I just went back to the normal motor brake.
Heres an updated picture of the truggy with the updated brake setup if your interested.
